  • Volume adjustment knob enables effortless volume setting

The dispensers use a re-circulation valve which prevents the loss of reagents during purging by re-directing them into the mounted bottle, thus facilitating bubble-free dispensing. A PTFE piston with ETP O-Ring, coupled with a unique Springless Valve™, facilitates effortless piston movement and ensures high chemical compatibility. VWR® Bottle Top Dispensers can also be used with solvents (refer to chemical compatibility chart). A specially designed volume adjustment knob allows 180° rotation for easy and effortless volume setting. It also has a flexible delivery nozzle that allows users to change the angle of dispensing.
